Looked like it wasn't health-related according to my source, Jeff Lockridge, at the Tennessean. Wanted to spend more time with his family though the timing of his decision was not good. There could have been some pressure from boosters after last year's debacle. Johnson wouldn't say. He was burned out. But if Caldwell can get it done or if Vandy goes after a guy like Kyle Whittingham of Utah, could be the best thing to happen to the program.
